Enmu

Enmu is a demon from Demon Slayer. And yes, Enmu is a boy (sorry for making it a girl it took me so long for me to make him in boy version). Enmu was first presented in the 2nd season of Demon Slayer. He can't tell whether it is reality or a dream, so his theme is a dream demon. He can make anyone fall asleep just by saying "Sleep!". Months ago, Muzan killed all of the Lowermoons due to the death of Lowermoon 5 or Rui, except for Enmu, since he saw a lot of potential in him. Muzan decided to give more of his blood to Enmu to become stronger. Enmu is now on Migwn train, making the people aboarding it, fall asleep in dreams so sweet, that they dont wanna wake up.
